She’s 100% alive, when el tried to stop kalis bleeding she got blood all over her hands, but when she’s with hopper on the roof and in the abyss, her hands are completely clean (kali getting shot was a illusion) and when the helicopter explodes that military dudes gun goes upwards above her head, not down, her being shot was a illusion to trick hopper into thinking Kali died and the el at the portal was real and also when it had a close up of her on the ground with her eyes closed implying she’s dead, she could’ve been with el in the void coming up with the plan, also el couldn’t use her powers with the kryptonite, it was impossible, and u can see Mike at the graduation start putting the pieces together, she wouldn’t of been able to use her powers, she didn’t have her blindfold on to pull him into the void in the first place AND her nose didn’t bleed, it bleeds EVERYTIME she goes there, even with Kali, and she doesn’t have her tattoo at the gate when she’s standing there, she also just vanishes? Instead of being sucked away into the void like everything else, she literally just disappears, AND a military guard literally pulled her out the truck and held her? U think he’s just gonna let her go and let her out of his site? el’s 100% alive, we hopefully getting that spin off with her and mike in like 5-6 years after the duffers are done with their paramount deal, this is all supported by Finn’s interview where he confirms/spoilers a spin off idea the duffers are planning when their all like 30 so in around 7-8 years possibly longer
